Description
Re-use/recycle write protected NFC Tags such as hotel key-cards, access badges, price tags, lift cards, key fobs etc... You can use this app to associate multiple functions (e.g. Wlan OFF, Bluetooth ON, Mobile Data TOGGLE, start navigation,run Tasker task, start any installed app, use media buttons, call a phone number, add a timestamp, calendar entry, add Text-to-Speech and much more!) to a NFC (near field communication) tag via an app internal database. You can even add tag cycles and let your tag run different activities per scan. So ReTag is the perfect NFC automation tool for you ;-).
(Works with ANY android supported tag = re-writable AND write protected!)
With NFC ReTag you don´t have to write anything on the tag (-> uses the tag ID, great for small tagsizes and write-protected tags!) and NO data is send to the internet. Additional write options (for better dispatching, device independent tags etc.) are also available. Import of activity tags and beaming is also supportet.
*!* NFC enabled device required / NO root required *!*

You could combine any activities and add as many activities and cycles as you want per tag. (obviously except for writing activity tags -> depends on tagsize). For best performance and dispatching, write a special NFC ReTag tag (this is NOT an activity tag!).

An ad supported free version (with limited number of tags) and an unlimited ad-free (PRO) version is available. Please check if this app works on your phone via the FREE version before downloading the PRO version.
Supports any standard android NFC tags (NFC Forum Type 1, Type 2, Type 3, Type 4 etc.).
Hints: Issues with TASKER: Install Tasker BEFORE NFC ReTAG, enable Misc / Allow External Access in Tasker UI, enable Tasker (on/off button), try the Tasker fallback option within NFC ReTag settings!
Some security related NFC Tags (e.g. in passports) change their ID on every read attempt. This app will not work with such tags.

Great idea and works flawlessly! Being able to repurpose RFID and NFC tags in new, useful and interesting ways can turn in to a full-blown hobby with this app! It's a delightful challenge to come up with triggers for all sorts of tasks especially once you add Tasker, IFTTT, and similar apps to your "projects". If you like to tinker with automation, you will love the possibilities this app opens up!

Galaxy S5 Great App, would like to see the pop-up when tag scanned done away with and just launch automatically.
★★☆☆☆Robert L Hughes· Sep 30, 2016
Problems My Galaxy Note 4 won't write tags with proficiency. Spent an hour scanning one tag and it still hasn't written. Two hours and five minutes and this program has only written 2 tags. 😠
★☆☆☆☆Marc Clarke· Jul 15, 2016
Mostly does not work on Note 3 Does not turn on GPS. Does not turn on mobile data.
★☆☆☆☆Mauricio Montoya Gil· Jan 15, 2020
It's supposed to rewrite NFC Tags, but you need to have the app installed to read the new written tags. So it can only be used by the owner of the app and not by other NFC devices

Lot of trackers in the app, that's not okay for a pro version. Found Trackers: 1. Google CrashLytics 2. Google AdMob 3. Google Firebase Analytics
